I dont think they are in split-brain. For split brain the flags should be mirror images: Example: trusted.afr.pfs-client-0 00 00 00 00 00 00 00 00 00 00 00 00 trusted.afr.pfs-client-1 00 00 00 00 00 00 00 01 00 00 00 00 trusted.afr.pfs-client-0 00 00 00 00 00 00 00 00 00 00 00 00 trusted.afr.pfs-client-1 00 00 00 00 00 00 00 01 00 00 00 00 Procedure to reset split-brain is to remove one of the files. 3.3 release onwards we need to also delete the file from gfid-backend. if the file is a.txt with gfid 5c71a049-a424-480e-9e69-2cdfd7a0a7a0 remove the file a.txt remove the file <brick-path>/.glusterfs/5c/71/5c71a049-a424-480e-9e69-2cdfd7a0a7a0 the gfid path is a hardlink to a.txt Pranith. ----- Original Message ----- From: "Emmanuel Dreyfus" <manu@xxxxxxxxxx> To: "Pranith Kumar Karampuri" <pkarampu@xxxxxxxxxx> Cc: gluster-devel@xxxxxxxxxx Sent: Tuesday, June 19, 2012 7:31:16 AM Subject: Re: split brain: how should it be cured?

How removing the file on one brick will make it recreated on the other one, but the split brain flag is sticky!
